9 Best Free Open Source File Renamer Software For Windows

Here is a list of best free open source file renamer software for Windows. These open source software are similar to standard file renamer software that let you rename multiple files at a time. Plus, you can also download and edit their source codes without any restrictions. In these software, you can either specify a naming pattern to rename multiple files or manually specify the names of all entered files. In the case of the naming pattern, you can specify a new name along with a pattern set like a number counter to maintain the similar file names across multiple files. Although if you want to rename files with a different set of names, then you need to manually specify new names for each input file in these software. In some software, you also get Expressions (%n, %e, etc.) to specify the naming pattern.

The process to rename multiple files at once is quite simple in all these software. Still, for novice users, I have included the basic file renaming steps in the description of each software. Apart from file renaming, these software also offers features to append file name, add text to file name, remove file names, add symbols to file name, etc. Go through the list to know more about these file renamer software.
